Holder for a surgical knife blade

Abstract

A holder for a surgical knife blade has a holder body, a slide member supported slidably by the blade storage barrel, an attaching finger formed in part of the slide member to attach the surgical knife blade, a slide operating piece integrally formed with the slide member, a lock hook member that prevents the slide member from sliding, locking concave grooves disposed in a slide guide edge of the holder body which guides the slide member slidably and engaging in the lock hook member, and a lever device, coupled to the slide member, for supporting the lock hook member while biasing the lock hook member toward the locking concave groove. The locking concave grooves are formed in an attachment position where the surgical knife blade is attached to the attaching finger in the slide member. In a storage position, the surgical knife blade is stored in the storage barrel.

Description

TECHNICAL FIELD[0001]The present invention relates to a surgical knife blade holder which accommodates a surgical knife for surgical operations, and which is a holder for surgical operations enabling a surgical knife blade stored in a storage case to be attached to a holder body with a single motion.BACKGROUND ART[0002]Conventionally, as a surgical knife used in surgical operations, there have been known two types that a handle portion to be grasped when used and a blade edge portion at the front end of the handle portion are formed integrally, and that a knife blade and a holder are formed separately while the knife blade is attached to the front end of the handle when used. The latter type of knife such that the handle and knife blade are manufactured and supplied separately and incorporated when used is widely used. When such a knife is a knife for work, the knife blade is exchanged with a new knife blade according to the wearing state of the blade edge. Meanwhile, when such a kn...

AI Technical Summary

Benefits of technology

[0010]Thus, in the holder for a surgical knife blade according to the invention, the slide member provided with the attaching finger is provided slidably in the blade storage barrel of the holder body, the slide operating piece for operating the slide member to slide is engaged and locked in the attachment position, use position and storage position in this order from the front end to the rear end side of the holder body by the lock hook member, the attaching finger is thereby locked in the attachment position reliably when the surgical knife blade is attached, and an operator grasps the holder body with one hand and fingers, while grasping the storage case with the other hand and fingers, and in this state, is capable of attaching the internal surgical knife blade by inserting the attaching finger of the holder body into the insertion guide hole of the storage case. Further, since the slide member provided with the attaching finger is engaged and locked in the attachment position, use position and storage position in this order after the attachment, it is made possible to operate the surgical knife blade with easy operation from attachment to a usage state, and further to a storage state after being used.

[0011]Then, the blade is attached to the holder body by inserting the attaching finger fixed into the attachment position of the holder body along the insertion guide hole formed in the storage case, and by pulling it, the surgical knife blade can be taken out of the storage case while being attached, whereby it is possible to attach the blade with a single motion. Accordingly, when attaching, the operator does not touch the surgical knife blade, is thereby safe, and does not have the risk of injury. Further, the risk is eliminated that bacteria and the like adhere to the surgical knife blade and result in infection.

Problems solved by technology

However, since the surgical knife is formed particularly acutely, there is a risk of injury such as hurt and the like when the surgical knife is attached or detached, and it is required to attach and detach the surgical knife safely and easily.
